scribed by Verrill under the name Glandula arenicola from specimens 
from Murray Bay, Gulf of Saint Lawrence. This species and Pandocia 
fibrosa are those for which Stimpson (1852) constituted the new genus 
Glandula (see p. 442). Traustedt (1880) redescribed this species from 
some of Stimpson's specimens, but erroneously stated that it had 
spiral stigmata. This supposed peculiarity caused Glandula to be 
recognized as a valid genus by many writers, until Hartmeyer (1909a) 
again studied the species, proving that its branchial sac was of the 
ordinary structure and that the genus Glandula should no longer be 
recognized. 
CyniMa vestita Stanger (1860) of the British coasts (Northumberland 
and Durham), described and figured by Alder and Hancock (1905- 
1907) as Stycla vestita, appears to be identical with this species. It was 
wrongly identified with Microcosmus glacialis (Sars) by Alder (1863). 
Tethymn molle is found from the Gulf of Saint Lawrence to Long 
Island Sound, inclusive, and according to Verrill (1874a, p. 352) down 
to depths of 150 fathoms though the writer has seen specimens only 
from rather shallow water. Verrill and Smith (1873) give the distri- 
bution as follows : " Murray Bay, Gulf of Saint Lawrence (Dr. J. W. 
Dawson). Saint George's Bank, 28 fathoms, sand, abundant (S. I. 
Smith). Off Cuttyhunk Island and Buzzards Bay (T. H. Prudden)." 
Verrill (1874a) records it from off Casco Bay, on muddy bottoms in 
from 50 to 95 fathoms and from east of Seguin Island, 23 fathoms 
(hard bottom with spots of mud). 
The writer has examined specimens from the following localities: 
Murray Bay, Gulf of Saint Lawrence (coll. by Dr. J. W. Dawson).

fathoms, sand and broken shells). 
Vineyard Sound. 
Buzzards Bay. 
Off Cuttyhunk Island. 
Station 788 (off Newport, R. I., 6 miles SSE. from Brenton's Reef Lightship,
